2. Safety
This chapter is intended for all users of the TFG telescopic pillar. It contains infor-
mation on its safe use and optimal utilization.
Safety program
The safety program from SKF Actuation System spells out who is entitled to use it and
the responsibility of individual users.
The TFG was designed and built in accordance with the latest technical standards and
accepted safety rules. The requirements of the stated standards were included and
checked as applicable (see Standards applied, page 40).
EU-conformity is documented with the technical documentation.
Purpose of the TFG
The telescopic pillar TFG has been designed and built to be operated in accordance with
its intended use. If you use the TFG for any use other than that cited, the manufacturer
cannot be held responsible for damage resulting from this.
The TFG has been specifically designed for the movement of patient tables, instrument
carriers, instrument tables, small lifting tables and dentist's chairs.
Intended use
The intended use of the TFG is:
■dynamic, compression or tension loaded stroke.
Please note: For the operations data, please see the Appendix of this operating
manual (see Equipment and operating data, page 33).
Unauthorized use
Any use other than the intended use without the manufacturer's written agreement or
operation beyond the technical limits is considered unauthorized.
You can find the technical operating limits in the appendix (Technical data, page 33) of
this manual and on the type plate of the TFG.
Please note: Any unauthorized use of the TFG can cause personal injury and prop-
erty damage. Always adhere to the instructions of this manual.

Safety
User groups
To ensure safety, we place requirements on the users of the TFG, that must be adhered
to under all circumstances. Only persons who meet the requirements are entitled to use
the TFG.
We refer to all persons who operate, use, commission the telescopic pillar, process it fur-
ther or pass it on for further processing as user groups. As the requirements of these
user groups strongly depend on their role, we distinguish between the following user
groups:
Operating authority
The operating authority is the contractual partner of the person doing the further pro-
cessing or the reseller. They can impose legal conditions on the operating authority
when purchasing the telescopic pillar. The operating authority ensures that the user is
instructed in the authorized use of the equipment.
Processor
The processor is the contractual partner of the reseller or the manufacturer. He assem-
bles the telescopic pillar into a complete device. He is authorized by the manufacturer to
use the telescopic pillar TFG in accordance with the regulations and has the necessary
expert knowledge.
Technician
The technician has the professional technical training to utilize the telescopic pillar TFG
according to its authorized use. Apart from the chapter on Safety, he is also familiar with
the chapter on Special operating modes. He will find the required technical data in the
Appendix.
Reseller
The reseller forwards the machine.
Operator
Any other person who uses the TFG is defined as an operator. The operator must have
read the Safety chapter in this manual before using the machine. Moreover, he must be
instructed about the normal operation by the operating authority.
Types of operation
intermittent, short-
term operation
The telescopic pillar TFG has been designed for intermittent or short-term use (see
Technical data, page 33).
Danger zones
We differentiate between two danger zones that must be observed, depending on user
role.
Persons
The danger zone covering persons also includes, in addition to the actual user, third per-
sons (other personnel, visitors, patients etc.). In case of injury, the operating authority is
liable.
Device
The danger zone device comes under the Processor and Technician user groups and cov-
ers the telescopic pillar TFG and any elements that have been attached.
Areas of responsibility
Different areas of responsibility, corresponding to the different user groups, arise.

effects of existing residual hazards. Pay attention to the residual hazards and the poten-
tial countermeasures given in the following chapters.

10
L5312,1675D.0/10.10
Safety
Residual hazards to people, objects and property
Pay attention to the following residual hazards and the possible countermeasures for
dealing with themTFG:
WARNING
Warning against hand injuries caused by trapping. Do not let any
object or person come into contact with the inner tube and/or the
final plate while the motor is running. Hold the TFG only by the ex-
ternal tube.
WARNING
Warning for risk of crushing and damage to the TFG caused by stat-
ic and dynamic overloading of the telescopic pillar. When driving
against fixed objects the impact of the force can cause personal in-
jury. Make sure that there are no persons or fixed objects present
in the danger zone during the stroke.
• Note the maximum permissible operating data in the Appen-
dix (see Equipment and operating data, page 33)
• Note the type plate of the telescopic pillar
WARNING
Warning of side-acting forces. Excessive side-acting forces destroy
the pillar and pose a danger to persons. During the stroke, do not
manipulate any of the elements that are connected to the TFG.
• You can find the maximum permissible values in the appendix
(see Equipment and operating data, page 33)
CAUTION
Beware of electric shock due to a squashed cable. Ensure that ca-
bles cannot get pinched or damaged. Check that the mains voltage
corresponds to the nominal value on the type plate. Ensure that the
strain relief clamp and cabling are correct.
